CVE-2026-63075
Issue summary: When OpenSSL processes QUIC traffic from a peer that repeatedly sends ack-eliciting packets while not acknowledging ACK-only responses, the QUIC stack can retain ACK-only packet metadata for the lifetime of the connection. Impact summary: A remote peer that can complete a QUIC...
CVE-2026-18798
Issue summary: QUIC server may double free QRX QUIC record layer RX object when channel creation fails for initial packet. Impact summary: Double free leads to heap corruption, which typically results in termination of QUIC server process, leading to Denial of Service. There is so far no evidence...
PT-2026-81306
Name of the Vulnerable Software and Affected Versions OpenSSL affected versions not specified Description When processing QUIC traffic, the QUIC stack may retain metadata for ACK-only packets for the entire duration of a connection if a peer repeatedly sends ack-eliciting packets without...
Astra Linux – Vulnerability in Firefox, NSS
Calling PK11Encrypt in NSS using CKMCHACHA20 and the same buffer for input and output can result in plaintext on an Intel Sandy Bridge processor. In Firefox, this only affects the QUIC header protection feature when the connection uses the ChaCha20-Poly1305 cipher suite. The most likely outcome i...
Astra Linux – Vulnerability in Chromium
The use of “after free” in QUIC in Google Chrome before version 124.0.6367.60 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption through a crafted HTML page. Chromium security severity: Medium...
Astra Linux – Vulnerability in Chromium
Using “after free” in QUIC in Google Chrome before version 148.0.7778.179 allowed a remote attacker to execute arbitrary code within a sandbox through malicious network traffic. Chromium security severity: High...
Astra Linux – Vulnerability in curl
libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified as an IP address in the URL. As a result, it does not detect impostor attacks or man-in-the-middle attacks...
Astra Linux – Vulnerability in Firefox
Data was not properly sanitized during the decoding of a QUIC ACK frame; this could have led to unrestricted memory consumption and a crash. This vulnerability affects Firefox versions earlier than 124...
Astra Linux – Vulnerability in Chromium
Insufficient validation of untrusted input in QUIC in Google Chrome prior to 97.0.4692.71 allowed a remote attacker to perform header splitting via malicious network traffic. Chromium security severity: Low...
CVE-2026-25800
A flaw was found in Quinn, a Rust implementation of the QUIC transport protocol. A remote attacker can exploit this vulnerability by sending specially crafted QUIC stream fragments with many gaps. This can lead to high buffer overhead in the Assembler component, causing memory exhaustion and a...

openssl: OpenSSL: Denial of Service via unbounded memory growth in QUIC server
A flaw was found in OpenSSL. A remote attacker could exploit this by sending a large number of QUIC Initial packets to an OpenSSL QUIC server. This can cause the server to allocate and queue new incoming channels without limit, leading to unbounded memory growth. The excessive memory consumption...
